Arturo Colombi (born January 6, 1958) is an Argentine Radical Civic Union (UCR) politician, and former governor of Corrientes Province.

He was elected governor of the province in 2005, when Ricardo Colombi resigned to stand for a seat in the Argentine Chamber of Deputies.

[1][2][3] In 2007, he successfully led the Corrientes Province party list supported by presidential candidate Cristina Fernández de Kirchner in elections to congressional seats, but was opposed by his cousin and former ally, Ricardo Colombi.

Like his ally, Vice-President Julio Cobos, Colombi became estranged from the Kirchners during the 2008 Argentine government conflict with the agricultural sector.

Amid both family and political acrimony, the latter won the election in the second round, and Arturo Colombi left office without attending his successor's inauguration.
